Patented Jan. 26, 1932 UNITED STATES PATENT OFFICE CHARLES W. GREEN, OF ILION, NEW YORK, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE NATIONAL CASH REGISTER COMPANY, OF DAYTON, OHIO, A CORPORATION OF MARYLAND CASH REGISTER Application filed. May 17,

This invention relates to improvements in cash registers or accounting machines and has more particular relation to improvements in the locking devices employed therein.

An object of the present invention is the provision of means for selectively locking any totalizer or corresponding device against operation without interfering with the usual operation of others of such devices and the 19 provision of mechanism whereby the proprietor or other authorized persons can conveniently render such means ineffective.

Another object is the provision of an improved construction of a centralized locking means for controlling the manner in which the machine is to be operated.

Still another object is to provide a secure and effective means for locking the various lids with which the machine is equipped, as

well. as means for permitting a salesman or is under control of the proprietor. is opened,

such as releasing a cabinet lid for exposure of the bank of item counters, operating a particular item counter, releasing the printing mechanism for taking totals accumulated by the counters and locking the machine against operation while the machine is in this condition.

Still another object of the present inven- 9 tion is to provide an effective means for preventing movement of the centralized locking lever from its adjusted position when one of the lids is in its open position.

With these and incidental objects in view the invention consists in certain novel features of construction and combination of parts, the essential elements of which are set forth in appended claims, and a preferred form of embodiment of which is hereafter described with reference to the drawings which 1923.

In the accompanying drawings the improvements are shown in connection with a machine of the general type fully shown in the U. S. patents to Frederick L. Fuller, Nos. 1,729,338 and Lid-2301, granted Sept. 4, 1929, and Jan. 7, 1930, respectively. Only such parts of the machine as are directly involved in the present invention are described herein,

however, and reference should be made to the patents mentioned for any information desired as to the construction and operation of the rest of the machine.

Although the improvements have been shown applied to the machine shown and described in the above cited patents, it is to be understood that the improvements are capable of being applied to or embodied in other forms of cash registers and accounting machines without departing from the spirit of the invention.

Described in general terms the illustrated machine comprises a series of manipulative devices such as keys 20 (Figs. 3 and 5) operable to actuate totalizing mechanism and mechanism for entering the items on a record strip. The keys 20 are pivoted upon a rod 21 and resting upon the rear ends of the keys is a key coupler 22 pivoted at 23. V-Jhen the outer ends of the keys are depressed the coupler is rocked counter-clockwise about its pivot (as viewed in Fig. 3) and its nose 2% enters the notches 25 in the rear ends of the keys. The construction and purpose of key coupler mechanisms are well known in the art and need not be discussed herein.

As shown in Fig. 3 each key 20 is formed with an upwardly extending arm 26 carrying a stud 27 engaging a slot 28 in a plate 29 rigidly mounted in a frame 30 loosely mounted on the shaft 31. The slots 28 in plates 29 are graduated so that each of the keys will impart a different degree of movement to the frame 30. The plates are furthermore provided with arcuate slots 36 to permit the upward tilting of the cam plates without interfering with the studs on the remaining un operated keys. Secured to the frame 30 is a segmental rack 311 (Fig. 1). t is to be understood that the keys 20 are arranged in banks and that for each bank there is a differentiallyactuated frame 30 and its corresponding segment rack. Each segment is always in mesh with a pinion rigid with its corresponding item type wheel 32 and sets up a number which corresponds to the value of the key depressed.

Connected to the key coupler 22 is a double rack 3-7 (Fig. 3), the connection being such that as the coupler is rocked by the keys the rackis raised or lowered, and drives a gear 38 secured to shaft 39 in such a manner that a complete reciprocation of the coupler will effect a complete rotation of the shaft. The shaft 39 carries cams and other devices for operating various parts of the mechanism. The mechanism for effecting rotation of the shaft has not been shown or described in detail because it is old and well known in the art.

In Figures 1 and 5 there are shown two keys 40 and 41 which are designated as clerks or coupler lifting keys. These keys, which are preferably located at the eX- treme left of thekeyboard, have certain functions, one of which is to serve as a means whereby the key coupler 22 may be partially raised to what may be termed the coupling position, in which position other keys representing the nature and amount of the transaction may be engaged with the coupler so that a complete operation of all the keys so engaged with the coupler may be effected by pressure applied to any one of such engaged keys.

The means whereby the coupler 22 is lifted to the coupling point comprises a coupler lifting cam surface 42 (Fig. 1) formed on the rear end of each of the clerks keys 40 and 41 and cooperating with a face 43 on a shoulder on the coupler 22 to lift the coupler until the portion 431 of the shoulder on the key coupler strikes the portion 432 on the key and stops the motion of the key and key coupler. The coupler is retained in its lifted position by the usual spring pressed pawl 4&1 (Fig. 3) engaging the teeth of a ratchet wheel 45 secured to the extreme right hand end of the rotation shaft 39. hen the key coupler has been so lifted and held, depression of the amount keys 20 will cause the notches 25 therein to engage spring pressed plates 4 .33 on the coupler.

Mounted below the item type carriers 32 previously mentioned and operable by the segmental racks 311 are two totalizer-s designated as totalizers A and B in Fig. 1. of the drawings. These may be utilized for the purpose of registering amounts for separate departments or clerks or to segregate the transactions in any other two classes, and they have manipulative means associated ther with in order that .ither totalizer may be operated to register amounts of the various transactions.

Totalizers A and B are pivotally mounted between side frames so that their pinions are capable of being rocked into engagement with their respective actuators. The engagement of the totalizer A with its actuator is under control of its corresponding clerks or coupler lifting key 40 while the totalizer B is placed in operation by means under control of its associated clerks or coupler lifting keyll. The engagement of the totalizer pinions with their associated actuators is effected during the time that the clerks or coupler lifting key is being depressed to its coupling position. Other keys may now be engaged with the coupler and upon further depression of one or more of such other keys the pinions will be actuated an amount commensurate with the value of the key or keys depressed. At the extreme end of the downward stroke, or, if desired during the first part of the upward stroke of the keys, the selected totalizer disengaged from the actuators and remains disengaged during the time the keys are returning to their normal position. The totalizer engaging and disengaging mechanism is not involved in the present invention and for a detailed description and showing reference may be had. to the above mentioned Patent 1,742,701.

As has been just stated, the entering of items into the totalizers is directly controlled by the clerks keys and in practical use each clerk is assigned a particular totalizer and corresponding clerks key so that the proprietor able to ascertain the amounts of sales of the respective clerks operating the machine and by simply adding together the amounts of the sales of the clerks the aggregate amount of business transacted by all the clerks during a particular period may readily be obtained.

In this particular type of machine where multiple totalizers are employed it is especially desirable that, in the absence of a certain clerk, the particular key assigned to that clerk shall be locked against operation in order to prevent fraudulent and improper manipulation of the machine.

One practical method for accomplishing the intended results is to provide the macl ine with locks which directly control the operation or non-operation of the clerks keys, each clerk, of course, being supplied with a key corresponding to the particular lock assigned to him. By means of this locking system each clerk is enabled to have entire control of his totalizer and when he off duty he is enabled to lock the key and totalizer assigned to him against operation and still allow the other clerks to operate their respective keys and totalizers in the usual manner.

The present invention is preferably used in connection with a cash register having multiple drawers so that there may be a drawer and corresponding totalizer for each clerk. hen this arrangement is used in connection with the locking system just explained each clerk will be directly responsible for the amount of sales transacted by him and is answerable to the proprietor for any discrepancy existing between the cash in his particular drawer and the amount standing on his corresponding totalizer.

As a precaution against one clerk surreptitiously operating a clerks key not assigned to him the following mechanism, which is best shown in Figs. 1. 4 and 5, is provided. Secured by any desirable means to the upper front of the enclosing cabinet are two locks 4.4 of the conventional type, the barrels of the locks projecting through the said cabinet to facilitate insertion of the keys of the respective locks. Mounted adjacent the clerks keys are levers the upper ends of which are held in engagement with the bolts of their respective locks by springs 46. The lower arm 47 of each lever is provided with a hook 48 and an arcuate slot 49 the purpose of which slot will. be explained hereinafter. Each clerks key is further provided with a projection 491 1). Normally, that is when the bolt of any lock is withdrawn, the projection 491 will be out of the path of the upper edge of the hook 48 and the clerks key may be operated in the regular manner; but when ever the clerk desires to lock his operatzng key, he inserts his key in the corresponding lock and projects the lock bolt, thereby b V ing the upper edge of the hook 48 under the stud 491 and preventing operation of the corresponding clerks key. It will be evident that this will have no effect upon the other clerks key and that the other clerk on duty can operate his key and totalizer in the usual way.

As so far described it is obvious that if all y the clerks happened to be off duty at a particular time the machine would be locked against operation and the proprietor would be unable to depress the keys and operate the mechanism in the usual manner without using duplicate lock keys. To give the proprietor a more convenient control over the clerks the following mechanism is employed.

Pivotally mounted upon the key shaft 21 is a bell crank 50 (Figs. 1 and 4) the arm 51 of which is provided with a stud 52 sufliciently long to engage shoulders 53 formed on the lower arms 47 of the locking levers 45. Directly underneath the key shaft 21 and journalled between the side frames is a shaft 54. Secured to the left end of the shaft is a cam in the path of the lower arm of the bell crank 50. When the shaft 54 is rotated, the stud 52 contacting with the shoulders 53 of the locking levers 47 forces the locking levers forwardly until the arcuate slots 49 therein are in the path of the studs 491 carried by the clerks keys. hen the parts are in this position the clerks keys may be depressed irrespective of whether the bolts ofthe clerks locks have been projected. The means for rotating the cam 55 to accomplish the results set forth is under control of the proprietor only and will be presently described.

The machine disclosed in the Fuller Patent 1,742,701, to which the invention is applied. ha. mechanism which controls the manner in which the machine is to be operated, as well as other functions such as locking the register. releasing the drawers, conditioning the machine for printing totals and resetting the totalizers and counters. This mechanism comprises a pointer 552 and lock 551 under control of the proprietor and situated at the right hand end of the machine (see Fig.

When the pointer 552 is adjacent the words lock register the machine is locked against operation. When the pointer is adjacent closed drawer the machine is conditioned so that it cannot be operated unless the drawer is closed. When the pointer is set in the open drawer position the machine is conditioned so that it can be operated while the drawer is open. The mechanism for accomplishing these results is not involved in the present invention, and for details of construction reference may be had to Patent 1,742,701.

'When the index is set opposite Unlock A & l the locked clerks toys are released for operation. The means for accomplishing this will now be explained in detail. Loosely mounted upon the shaft 31 is an adjustable bell crank 56 (Figs. 3 and 4) and secured to the said bell crank is a curved plate 57. The plate carries the pointer or index 62 integral with the adjustable plate 57 thus guiding the plate 57 in its movement.

Fastened to the adjustable plate 57 by any desirable means is the lock 551, the barrel of which projects through and is capable of moving in an elongated slot 610 (Fig. formed in the cabinet of the machine. The rotatable bolt of the lock is provided with a flange 58 (Fig. capable of registering with a series of notches 63 formed on the plate 60. The flange 58 is further provided with a slot so arranged and constructed that when the bolt is rotated by manipulation of the inserted key the said slot and plate 60 are placed in alinement and the bolt and parts carried thereby are released for adjustment. When the pointer is set to the desired position the key and bolt are again rotated so that the fiange58 of the bolt cooperates with the proper notches 63 whereby the adjusted bell crank will be locked against movement when the key is withdrawn.

For aligning the bell crank 56 a spring urged pawl 64 pivoted upon the bell crank 56 isprovided. The pawl 64 engages notches 65 formed upon .the lower edge of the plate 60 to hold the adjustable bell crank in its set position.

The lower arm of the bell crank 56 is provided with anextending sector arm 66 (Figs. 3 and 4) carrying teeth 67. Mounted loosely on'the key shaft 21 is agear sector 68 mesh ing with the teeth 67 of sector arm 66 and secured to the gear 68 is a somewhat larger gear sector '69 meshing with a gear sector 70 secured to theright hand end of the shaft 54 herinhefore mentioned. From the foregoing it is evident that when the proprietor manipulates the bell crank 56 so that the index is adjacent Unlock A & B the shaft 54 will be rocked by means of the train of mechanism just described, to actuate the cam 55 to disable the locking levers 45 for release of any locked clerks keys.

In the Fuller Patent 1,742,701 there is provided a suitable printing mechanism for printing upon a record strip the amount, nature of the transaction and a special character identifying the clerk operating the machine. The printing mechanism of the present application is pivotally mounted upon the shaft 31 and is capable of being rocked forwardly over the respective totalizers A and B in order that the amount standing thereon can be printed upon the record strip. The machine is further provided with the so called autographic feature, or a device whereby a written entry may be made to identify the same with some particular sale or person. (See Fig. 5.)

The printing mechanism is not fully disclosed in this application but a part of one of the pivoted frames thereof is shown at 701 (Fig. 4) and the record strip is shown diagrammatically in Fig. .3, reference character indicating the supply roll and 76 the storage roll, the direction of the feed being designated by the arrows. The supply and storage rolls are mounted upon a separate frame which is pivoted upon the side frame 701 of the printer mechanism so that this separate frame may be swung around its pivot to an upward position for replenishing the paper supply or removing the printed record strip. Directly over the printing mechanism and record strip is a flat lid or writing table 78 (Figs. 1, 3 and hinged at its rearward end and provided with a glass 79 through which printed items are visible. The glass is further provided with a writing slot 80 to permit the entering of the notations adjacent the printed items. By lifting up this lid access may be had to the printer when it is necessary to replenish the supply of paper.

Located in the central part of the machine and directly over the keys 20 is a second lid 82 (Figs. 1 and hinged at its lower end. This lid is equipped with a shield or cover 83 overlying the totalizers. It is desirable, of course, to have the locks so constructed that a clerk may be able to open the writing table lid 78 for replacing the record strip, but he should be unable to open the lid 82 which would give him access to the totalizers. The details of the novel mechanism devised to accomplish the desired results will now be set forth.

Suitably ournalled between the side plates of the front lid 82 is a rock shaft 85 (Figs. 1 and secured to the extreme ends of which are two locking spiders 86 and 87 urged rearwardly by spring 951. Each spider comprises an upwardly extending hook 88 engaging a locking lug 89 secured to the upper lid 78 and a downwardly extending hook 90 engaging a transversely extending lug 91 carried by the cabinet proper. As is evident from Fig. 1, the hook 88 is somewhat shorter than the hook 90 so that if the spiders are rocked a short distance they will permit the opening of the upper lid, but the hook 90 will not have been released from the locking lug 91, and will not, therefore, permit opening of the lower lid 82. For the purpose of permitting this partial rocking of the locking spiders there is secured to the shaft substantially midway a releasing finger 92 (Fig. 5) suitably disposed underneath a bolt of a lock 93. The travel of the bolt is sufficient to actuate the releasing finger 92 to rock shaft yrs six

85 to withdraw the book 88 but not suflicient to withdraw the hook 90. It will be clear that the clerk or whoever is provided with the key of the lock 93 will be able to gain access to the upper lid to replenish the paper supply, etc., but cannot obtain access to the totalizers or to the printing mechanism to obtain the totals standing on the totalizers. The spider 87 is provided with a nose 941 which will engage a stud 95 and prevent further rocking of the spider 87, shaft 85 and parts carried thereby.

At the end of the days business or any other desired period the proprietor opens both of the lids just referred to, obtains the totals accumulated on the totalizer and then resets the same to zero. The means whereby the proprietor can accomplish the above is uncer control of the lock 551 above mentioned.

The index is set opposite adjacent the word reset and through the medium of sector 60, gears 68, 69 and the shaft 54- is rocked counter-clockwise as viewed in Fig. 1. Shaft 54 has secured thereto a disk 97 (Figs. 1 and 4') formed with a cam slot 98 in which registers a stud carried by a bell crank 99. 1V hen the index is set to the reset position, the bell crank 99 will be moved rearwa-rdly by the train of mechanism just described to bring the stud 95 into a notch 100 simultaneously rotating the spiders 86 and 87 su'liiciently far enough tov unlock both lids.

When the lower lid is opened certain mech anism comes into play whereby the latch for the special counter lid is released, the counter for indicatingthe number of times the lower lid is opened is actuated, the printer frame is released for obtaining totals, the operating mechanism is locked against movement and the centralized locking mechanism is prevented from being moved from reset position as long as the lower lid is in its open position. The mechanism for accomplishing all this will now be taken up in order.

Extending transversely between the side frames and suitably.journalled in lugs 101 (Fig. 1) is a shaft 102, (see also Fig. 4) and in longitudinal alinement with the said shaft is a second shaft 103 journalled in a similar manner. Shaft 103 terminates at a point 10% (Fig. 2) but is capable of rotating with the shaft 102 by means which will presently be des ribed. The shaft 102 carries a plate 105 having a cam slot which registers with a stud 1051 (Fig. carried by an arm secured to the lower lid 82 so that as the lid is reciprocated the shafts will be rocked simultaneously. V

In registers of this class it is usual to provide item counters for counting the number of times certain operations and transactions are performed. An item counter is provided in the present machine for indicating the number of times the lower lid is opened. Th 1 s counter and the other counters mentioned for counting the various kinds of operation of the machine are covered by a suitable lid hinged to the cabinet, the counter lid being opened each time that the lower lid is opened. The counter -id 100 is shown in Fig. 5 and the counter and part of the operating lever is illustrated in Fig. 1. A latch 107 urged forwardly by a spring 108 4) is looseiy mounted upon shaft 102. A pin 109 secured to the latch 10? is urged forwardly by the said spring 108, so that it contacts with the edge of an arm 110 secured to the rock shaft 102. From this it is evident that whenever shaft 102 is rocked by opening the lower lid 82 the latch 107 will be retracted to release the speeial counter lid.

For actuating the counter 1110 (Fig. 1) there is provided a link 111 articulated to the operating arm 110 and slidably mounted at its rearward en l. The rearward end of link 111 has suitable connections to an item countr 1110 (Fig. 1) of a conventional type so that each time the lower lid 82 is opened a unit is added to the item counter.

[is has been explained heretofore, in order to print the totals standing on the totalizers the printer frame is rocked forwardly over e respective totalizer. lVhen in this position platen will be actuated by a hammer so that the total accumulated on the totalizer will be printed upon the record strip. Normally, that is when the lower lid 82 is closed, the printer frame will be locked against such movement.

The printer frame 701 is equipped with a stud or projection 112 (Fig. 4;) which normally has in its path an obstructing arm 113 secured to rock shaft 103. A spring 114 interposel between the arm 113 and another arm 115 secured to the shaft 102 draws the arm 113 down vardly so that its lower edge contacts with 2. lug 116 formed on a projeetion of the arm 115. From this it is evident that the shafts 102 and 103 may be rocked simultaneously or if shaft 103 is held inimovable for any reason whatsoever, the rock shaft 102 could be rocked independently. The reason for tne flexible connection between the two shafts will appear later. From the fore going it is clear that whenever the lower lid 82 is opened and the arm 113 is rocked downwardly to clear the projection 112 the printing mechanism is free to be rocked forward for printing the totals on the record strip.

WVliile the totals are being printed it is very desirable that the keys be locked against operation. This is performed by an arm 117 secured to the extreme end of shaft 103 (Fig. 1) which moves downwardly in the path of a projection 11.8 integral with the coupler 22 whenever the lower lid 82 is opened, thus locking the keys and operating mechanism against operation.

The forward edge of the arm or projection 118 is concentric with respect to shaft 103 and whenever the machine is operated the coupler 22 will be lifted and the arm 118 will pass under the arm 117. It for any reason the coupler should be held upwardly by a partial depression of any keys and if the shafts 102 and 103 were integral, access to the lower lid would be prevented since the plate 105 would be locked. By virtue of the flexible connection between the shafts 102 and 103 the lower lid may be opened during the time the operating keys are displaced from their normal position. This facilitates the release of the operating mechanism in the event that the parts should become jammed during an operation of the keys, and if it were not for this feature it would be necessary to remove the cabinet to gain access to the mechanism.

The reciprocating of the lower lid to its open position will also lock the centralized lock mechanism against adjustment from its reset position. The devices for accomplishing this are best shown in Fig. 6, the lid being illustrated in its open position. Secured to or integral with the shield 83 is a plate 120 the latter being provided with forward and rearward extensions 12-1 and 122 respectively at substantially right angles to the said plate 120. The upper edges of the extensions are substantially concentric with the hinges of the lid 82 and when the latter is open these edges are slightly above the line of travel'of .a lug 123 formed upon the upper end of the bell crank 99. Therefore when the lower lid is opened as clearly shown in Fig. 6, the lug 123 is to the rear of the extension 122 thus locking bell crank 99, and through the connections previously mentioned preventing movement otthe centrali zed locking element 56. As the lid is moved to its rearward or closed position the rear end of extension 122 back of the concentric edge will force the bell crank slightly to the rear. The concentric edge will then pass under and in contact with member 56 and lock this member against movement until the lid is completely closed. When the lid is completely closed and the control lever is out of the resetting position the lug 123 is directly over the extension 121 as shown best in Fig. l of the drawings. Therefore when the centralized locking member is in any other position than reset the In 123 overlyin the D i b 3 extension 121 will also serve as a very ei fective lock against any fraudulent opening of the lower lid 82 by unauthorized persons. It is understood, of course, that when the ma chine is placed in the reset condition the bell crank 99 will be moved rearwardly so that lug 123 clears the extension 121 thus releasing the lower and upper lids in the manner previously described.

Fig. 7 illustrates quite clearly the relative position of the parts just referred to at various stages in their operation. Normally the lug 123 is in the broken line position indicated in this figure, While the plate 120 and lid 82 are in the position shown in full lines, wherein the co-operation of the forward end of extension 121 with the lug 123 prevents opening of the lid. Movement of the element 57 to the reset position will place the lug 123 in the full line position shown, wherein it will not interfere with the rocking of the extensions 121 and 122 and hence the opening of the lid 82. On the other hand, when the latter is opened the extensions 121, 122 will be in the broken line position indicated and it will not be possible to return the lug 123 to its broken line position so that the element 57 will also be locked.

It is thought that the operation of the devices is set out in such detail in the foregoing description as not to require the usual summary of the operation of the machine.
